Heated Glass Element Relay: Testing and Inspection

WINDSHIELD / WINDOWGLASS: DEFOGGER RELAY: ON-VEHICLE INSPECTION

1. INSPECT MAIN BODY ECU (DEFOGGER RELAY)





(a) Remove the DEF fuse.

(b) Using an ohmmeter, measure the resistance between the terminals of the DEF fuse.

Standard resistance:

Below 1 Ohms

(c) Install the DEF fuse.

(d) Using an ohmmeter, measure the resistance between terminals 4Q-12 and 4Q-4 of the main body ECU connector.

Standard resistance:

Below 1 Ohms

(e) Turn the ignition switch ON.

(f) Turn the defogger switch ON.

(g) Using a voltmeter, measure the voltage between terminal 4F-2 of the main body ECU connector and body ground.

Standard voltage:

11 to 14 V
